The small little wheels that came with the furniture mover I bought were too small for me. I use a moving truck to set up a 55 gallon trash can. I keep Black Oil sunflower seeds in the bin to feed the birds around my house. I keep birdseed on a cart in the barn along with a golf cart and a 4 wheeler. To get my ATV out of the shed, I have to move the trash can 55 gallons. These four 3 inch trolleys make it easy. I then bought four more to put under my LCA Ultimate EZ Bow Press so I can easily move them around the barn too. They did a great job on that too.
